Arms 54, 55, are fixed to the rocker-rods, being shown integral with the hubs 47, 48, and arms 56, 57, extend integrally from hubs 58, 59, fixed to the opposite ends of the rocker-rods. The arms 54, 55, 56, 57, areprovided with slots 61, 62, extending radially from the pivots of said arms, that is, from the rocker-rods. Pins 63, 64, are fiXed in the punch frame and are located in said slots.

Rocking of the rocker-rods causes up and down.

rocking movements of the arms, thereby. moving the punch frame up or down on the upright posts 12, 13, guided by the bearings 32 about saidposts.

Cushion washers surround the posts.

' Suitable means may be provided'for operating the rocker-rods, exemplified as an operating arm 67 having a hub 68 fixed to one of the rocker-rods,

and a handle 69 for manually. manipulatingthe same.

= 1 1. The die-plate 35 is provided with ledges 66 overin the slot-between said die plate and marginal A punch-frame '71 has a series ofpunches 72 v and a master punch 73.therein.' The series of punches maybe termed junior punches. They are arranged'in rows, preferably of ten punches each,-a suitable number of rows being provided,

twelve of these being shown. The punches are arranged to have reciprocating movement relativeto theframe. l.

The punch-frame comprises a skeleton frame 1 '74, a plate '75 at the-top of the latter secured thereto, as by screws 76, and a plate '77 at the 1 bottom ofthe framesecured thereto as by screws '78. The plates are provided'with registering holes 79, 80. l The-punches of the series ofpunches are guided in the registering holes '79; 80. The master punch isguided in registering holes 81, 82,- in said plates. The'punches are in the form of stems guided in said holes. They have cutting 11 edges at their lower ends which coact with the cutting edges of the punch-holesin the die-plate for cutting the sheet. The masterpunch is exemplified as cutting a slotand the series of punches, or junior punches, as cutting smaller holes.

There is a sheet-receiving space 85 between the by strips-.86, 87, the inner marginsof which form .said'plates, so as tocause registry of thesheet in correct rel'ationin said space for punching the 1 holes therein in correct positions. The plates 35, 75, 77, the gage-strips 86, 87, and the frames 31,

'71, may be rigidly secured together .by screws 88 for causing all of these parts to move together.

when'operating the operating handle. The post 12 is=a short post, being located wholly under the space 85;

The junior punches are retracted in the punch frame; as by helical springs 91 surrounding the same and located between the plate =77 and a washer 92 positioned on the punch by a pin 93. The pin acts as a stop.against;-the-plate to limit upward movement. of the punch. I

. The master punch is retractedv in the punch punch between the platez'l'land awasher95 loof the master-punch.

Selector means are provided for selecting which of the punches in the series of punches are to be operated, and, in the present exemplification tripping or clearing mechanism is provided in each of the rows of selector parts, so that when one of the selector parts in any row is operated, the balance of the selector parts therein are released. The selector parts are arranged in rows complemental to the punches in the respective rows of punches. l a

The selector parts are exemplified as bars 101. These bars are arranged to be placed in coactive relations with the respective punches of the series of punches. They are shown mounted in a selector frame 102 provided with bearings 103 at three of its corners received about the upper ends of the posts 13 andfixed to said posts as by setscrews 104. Guide bars 105, 106, are secured rescrews for clamping the parts together. hanging 'themarginalfianges 16 of-the'base for "preventing pinching of the. fingers of. the operator The bars 105, 106, .are provided with notches .111, 112, in which the shanks of the bars 101 received through said bars locate said washers, and limit upward movements of the bars by contact with the lower faces of the bars 105.

The bars 101 are provided with projections 118 having shoulders 119 received under pins 120 on slide-bars 121, the projections having inclined edges 122 for moving the pins laterally, in order that they may be retracted above the shoulders 119 when the *bars 101 have been sufiiciently depressed. I Y

The slide bars 121 are reciprocable in bearings formed by the depending ends 123 of the bars 106, these depending ends being. provided with notches 124 forming lower lugs 125 on which the lower edges of the slide bars rest, the upperedges of the slide'bars being guided by the bodies of the bars 105, and the side faces of said slide bars being guided by the bottoms of the notches 124 and the edge ofrthe depending end 123 adjacent thereto. The structure forms slots in which the slide bars move. Eachof the slide bars is provided with a positioning pin 120 for each of the control bars 101 in the row of control bars affected thereby.

Each of the slide bars has its end bent to form a lug 131, in-which thereis a pin 132, which is received in a hole 133. in thedepending lug 123 of the bar 106. A helical spring 134 surrounds said pin and normally urges the slide bar in onedirection for placing the pins thereon against one of the edges of the bar101, andnormally urges the pin into position above the shoulder 119 thereon when the" control. barisidepressed into :coactive relation withflits corresponding punch.
